Krishna - Horse Slayer

In the tenth Book of the Bhagavata Purana, Krishna himself waged war on the four legged sinner—a horse named Keshi, who gallops at the speed of thought, scatters into chaos celestial vehicles and the clouds in the sky with his dirty, filthy mane—whose neighing terrifies the people of earth. 

Krishna challenges Keshi to a duel, as the horse is creating havoc around Gokula. Keshi roars and charges towards Krishna, striking him with his hooves. Krishna catches hold of Keshi's two legs and tosses him to a great distance. 

Recovering from the fall, the agitated Keshi opens his mouth and attacks Krishna but Krishna thrusts his left arm into Keshi's mouth, and all of Keshi's teeth fall out as if he'd used a bad toothbrush. Krishna's arm expands to the size of a boa, and Keshi chokes. He kicks his feet in struggle.  His eyes roll back into his skull. Keshi falls to the ground, dead.

Depicted above and below being attacked by Keshi, Krishna slays our common foe with a mighty arm.
